Most message boards I belong to -- including coin ones -- DO accept PDFs and Word docs. It's actually pictures that can take up more space, it takes lots of text/words/pages to be the same file size as a high-def or raw pic of a coin.
If I have to use DropBox or something like that, that would be my poor 2nd option.
BTW, the "research" is more compendiums of articles, commentaries, research links, etc (esp. from the Heritage Archives)....don't want to confuse it with the type of research you do, Roger. But I still think it will be of interest to Saint/Double Eagle afficionados.
